Diadema sea urchins (Diadema antillarum) are important algae grazers, but restoration attempts often record low survival of restocked individuals. This article sheds light on one of the causes for unsuccessful restocking. Restocked sea urchins were monitored with time-lapse cameras for 10 days. There …

Handelscontrole vanuit zee was een integraal onderdeel van de militaire inzet in Atjeh en moest bijdragen aan de onderwerping aan de Nederlandse soevereiniteit. Deze maritieme inzet wordt vaak veralgemeniseerd tot ‘de blokkade van Atjeh’.[6] Maar wie het conflict onder de loep neemt, ziet dat niet alleen …

This thesis is a literature review on the impact of global warming on the great whale pump in Europe. Global warming is known to have an effect on different ecosystems around the world. However, what is largely unknown is the impact of global warming on marine systems and specifically large whales that …

In Nederland wordt veel ecologisch onderzoek gedaan naar vissen, vaak gericht op het migratiegedrag en de belemmeringen die vissen tegenkomen wanneer ze tussen de verschillende leefgebieden migreren. Als vissen worden voorzien van zenders of merkjes staat het welzijn hierbij centraal.

In de middeleeuwen was geweld op de zeeën rondom Europa endemisch. Piraterij was de norm. Scheepvaart en geweld gingen hand in hand. In de Lage Landen was het niet anders. Vanaf de vorming van de kustgraafschappen tot aan de Nederlandse Opstand waren handel, zeeroof en maritieme oorlogvoering onlosmakelijk …

Nature-based strategies, such as wave attenuation by tidal marshes, are increasingly proposed as a complement to mitigate the risks of failure of engineered flood defense structures such as levees. However, recent analysis of historic coastal storms revealed smaller dike breach dimensions if there were …

The massive die-off of the sea urchin Diadema antillarum in 1983–1984 is one the main reasons for low coral recruitment and little coral recovery in the Caribbean. As the natural recovery of D. antillarum is slow to non-existent, multiple restoration studies have been attempted. There are currently three …

This thesis provides an answer to the question if the International Council for the Exploration of the Sea (ICES) does fulfil its own objective of supporting Ecosystem-based management by producing Ecosystem Overviews as advice. Against the background of ongoing changes and pressures on the ecosystem, …

Cetaceans play an important role in the functioning of natural ecosystems. The Caribbean Sea serves as an important foraging, breeding, and birthing area for an array of cetaceans, which led to the establishment of the Yarari Marine Mammal Sanctuary in 2015. Currently, no additional conservation measures …

Marine spatial planning (MSP) was developed as a place-based, integrated marine governance approach to address sectoral and fragmented management issues and has seen significant evolvement over the past two decades. MSP has rapidly become the most commonly endorsed management regime for sustainable development …
